Answer: The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.
Step-by-step explanation:
A rectangle is a 4 sides closed quadrilateral where opposite sides are equal .
So , length of one pair of opposite is represented by 'l' [l= length]
Such that sum of these two sides = l+l=2l
The other pair of opposite sides s represented by 'w' [w= width]
Such that sum of these two sides = w+w=2w
Perimeter is the sum of sides.
So, perimeter of rectangle = 2l+2w.
The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.
How many solutions does this system of equations have?
A. No Solutions
B. 2
C. 1
D. An infinite number of solutions
===================================================
Explanation:
Let's solve the first equation for y
4x - 2y = 6
4x-6 = 2y
2y = 4x-6
y = (4x-6)/2
y = (4x/2) - (6/2)
y = 2x - 3
After doing so, we see that 4x-2y = 6 is equivalent to y = 2x-3
Therefore, the original system of equations is effectively listing the same equation twice (one has a different form compared to the other).
Both equations in this system produce the same graph, which leads to infinitely many solutions. All solutions are on the line y = 2x-3.
You can say that all solutions are in the form (x, 2x-3) where x is any real number you want.
-------------------------------
Here's another approach using substitution
4x - 2y = 6 ... start with the first equation
4x - 2( y ) = 6
4x - 2( 2x-3 ) = 6 .... replace y with 2x-3; ie plug in y = 2x-3
4x - 2(2x) - 2(-3) = 6
4x - 4x + 6 = 6
0x + 6 = 6
0 + 6 = 6
6 = 6
We get a true statement. The last equation is always true regardless of what we plug in for x, so this is another way to see how we get to infinitely many solutions.
Side note: the system is considered dependent since one equation depends on the other. The system is also consistent since it has at least one solution.
determine the measure of angle a. PLEASE HELP ASAP!
a.64 degrees
b.45 degrees
c.88 degrees
d.42 degrees
Answer:
D
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle will always total 180.
Therefore:
[tex](9x+6)+(74)+(16x)=180\\[/tex]
Let’s solve for x:
Combine LIke Terms:
[tex](9x+16x)+(74+6)=180[/tex]
Add:
[tex]25x+80=180[/tex]
Subtract 80 from both sides:
[tex]25x=100[/tex]
Divide both sides by 25:
[tex]x=4[/tex]
Therefore, the value of x is 4.
Now, to find A, we can substitute it for A.
A is measured by:
[tex]\angle A=9x+6[/tex]
Substitute 4 for x and evaluate:
[tex]\angle A=9(4)+6=36+6=42\textdegree[/tex]
Hence, our answer is D.

3/4 of 24 is___ and 2 3/4 of 24 is___
Answer:
3/4 of 24 is 18 and 2 and 3/4 (11/4) of 24 is 66.
Step-by-step explanation:
First, divide 24/4.
24/4 = 6
Multiply by 3.
6 x 3 = 18 ( or 24 x 3/4 )
2 and 3/4, or 11/4 = 2.75.
Multiply 24 by 2.75 (or 11/4) to get 66

Geraldo has a gold chain that is 34 inches long. He cuts it into 2-inch-long chains. How many gold
chains does Geraldo have now?
Geraldo has 17 gold chains as calculated by the basic arithmetic operation of division.
Division is an arithmetic operation in which a number is broken down into smaller pieces.
One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.The other operations are multiplication, addition, and subtraction.In its most basic form, the division of two natural numbers involves, among other things, counting how many times one number appears inside another. This count does not necessarily have to be an integer.The number that is divided is called the dividend, the number that is dividing is called divisor and the quotient is the number that is result of the division.Now Geraldo has a 34 inch long gold chain. Therefore if he cuts it into 2-inch long pieces then we will divide 34 by 2 and the quotient will give us the number of chains.
∴ 34 ÷ 2 = 17
Hence Geraldo will have 17 chains.

Jonas has been saving for a video game . last year it costs $28 this year it costs $36 find the percent of change in the cost .
Answer:
Last year the cost was $28.
This year the cost is $36.
$36 - $28 = $8
Percent of increase = amount of increase ÷ original amount
$8/$28 = $0.286
$0.286 · 100 = 28.6%
There has been a 28.6% of change in the cost.

Which value of x makes the equation 0.5(x + 15) = 2 + 0.75(x - 4) true?
Answer:
Step-by-step explanation:
[tex]\frac{1}{2}(x+15) = 2 + \frac{3}{4}(x-4)[/tex]
To make this easier, to get ride of the fractions, we can multiply both sides by 4
[tex]2(x+15) = 8 + 3(x-4)[/tex]
now use the distributive property
[tex]2x + 30 = 8 + 3x - 12\\[/tex]
now we want to isolate x to one side and isolate all the constants to the other
[tex]2x - 3x = 8 - 12 - 30\\[/tex]
now simplify
[tex]-x = -34\\x = 34[/tex]
to test, we can plug in back to the original
[tex]\frac{1}{2}(34+15) = \frac{49}{2}\\\frac{8}{4} + \frac{3}{4}(34-4) = \frac{8}{4} + \frac{90}{4} = \frac{98}{4} = \frac{49}{2}[/tex]
it works

what is the solution for x in the equation?
Answer:
3
Step-by-step explanation:
combine like terms (so 1/2 and 3/2): 2 - x = x - 4
add x to both sides: 2 = 2x - 4
add 4 to both sides: 6 = 2x
divide both sides by 2: 3 = x

Use two sets of coordinates to write an equation
to describe the relationship.
Answer/Step-by-step explanation:
An equation that describes the relationship can be written as [tex] y = mx [/tex].
Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:
[tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70 [/tex]
Substitute m = 70 into [tex] y = mx [/tex]
The equation would be:
[tex] y = 70x [/tex]
This equation can be interpreted as follows:
